CHURN.

SPECIFICATION forming'part of-LettersPatent No. 619,811, dated February 21, 1899. Application filed February 11,1898. Serial No. 669,968. (No model.)

To all whom it may concern:

Be it known that LWILLIAM ELIAS VERNON, a citizen of the United States, residing at Oskaloosa, in the county of Mahaska and State of Iowa, have invented. a new and useful Churn, of which the following is a specification.

My invention relates to churns, and has for its object to provide a simple, compact, and efficient construction and arrangement of parts adapted for facilitating the separation of butter with the minimum exertion and expenditure of time on the part of the operator, and, furthermore, to provide such a construction as to facilitate the cleansing of those parts exposed to contact with the contents of the receptacle.

Further objects and advantages of this invention will appear in the following description, and the novel features thereof will be particularly pointed out in the appended claim.

In the drawings, Figure 1 isa verticalcentral section of a churn constructed in accordance With my invention. Fig. 2 is a view of the dasher detached.

Similar numerals of reference indicate corresponding parts in all the figures of the drawings.

1 designates a receptacle, of which the top is closed by a cover 2, having exterior pendent flanges 3, and supported by this cover is a bracket having a horizontal bearing-bar 4, terminally downturned, as at 5, and secured to the flanges of the cover at diametrically opposite points, and uprights 6, connected by a cross-bar 7. In suitable vertically-alined bearings on the bracket is mounted a dasherstaff 8, provided atits upper end with a bevelpinion 9, with which meshes a bevel-gear 10, carried by a counter-shaft 11, said countershaft being mounted in horizontally-alined bearings in said uprights. Also mounted in horizontally=alined bearings in the uprights, below the plane of the counter shaft, is a spindle 12 of an internal master-gear 13, meshing with a pinion 14 on the contiguous extremity of the counter-shaft. It will be seen that this construction provides spaced bearings for each of the shafts, including the spindle of the master-gear, and hence insures the proper codperation of the gears, While the entire operating mechanism is carried by the cover of the churn-receptacle and is removable therewith.

Removably and adjustably mounted upon the dasher-shaft is a dasher 15 of truncoconical construction,with its upper end closed and its lower enlarged end open and in communication with the interior of the receptacle. This dasheris provided at its upper end with a hub or socket 16, which is fitted upon the dasher-shaft and is adapted to be secured at the desired adjustment by means of a thumbscrew 17.

The dasheris provided with alternatelydisposed exterior spiral ribs 18 and vertical series of openings 19, the series of openings in the dasher illustrated being arranged at diametrically opposite points, and the upper and lower extremities of the interposed spiral ribs being located, respectively, at the upper and lower ends of the said series of openings, each rib thus extending around one-half of the circumference of the dasher.

The rotation of the dasher being preferably in the direction indicated by the arrow in Fig. 2, it is obvious that the ribs will exert a downward pressure upon the exterior surrounding portions of the contents of the receptacle, and hence the discharge of liquid downwardly from the interior of the dasher will be prevented by theribs from boiling over the sides of the receptacle, and at the same time will be thoroughly agitated. The liquid in the receptacle outside of the dasher will be inducted, together with atmospheric air, through the openings in the side wall of the dasher and will then be discharged downwardly, as above indicated. Thus in operation the contents of the receptacle are maintained in an agitated condition calculated to insure the rapid separation of the butter, and the efficiency of this operation is increased by employing a cross-sectionally rectangular receptac1e,whereby as the liquid is discharged downwardly from the dasher it is caused to boil up at the angles of the receptacle.

dasher closed at its upper and open at its lower end and enlarged downwardly or toward said open end, the side wall of the dasher being provided with alternately-disposed exterior spiral ribs and vertical series of openings, the extremities of said ribs being located at the opposite ends of alternate series of openings, substantially as specified.

In testimony that I claim the foregoing as my own I have hereto afiixed my signature in the presence of two witnesses.

WVILLIAM ELIAS VERNON.
